A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Integrated screening and CRISPR reveal eleven previously unknown factors essential for early embryo development. They showed ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

New insights into a sophisticated process that protects sperm cells has revealed a mechanism, similar to an immune system, thwarts genetic chaos during the earliest stages of their development.

The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...
